I remember using it in geometry, but i forgot why we used it. Can someone explain why AND how each is used. (on a regular scientific calc..not graphing.) oh and i know that there was a way of finding the measure of lines for exapmle, like Sine was the opposite angle and hypotenuse or something (correct me if im wrong) and there was a way to remember it that was similar to socahtoa. please i have FCATs next week and thats supposodly on it.

It's SOH - CAH - TOA
Sin=Opp/Hyp
Cos=Adj/Hyp
Tan=Sin/Cos-Opp/Adj
Opposite is the angle facing the angle
Adjacent is the angle next to the angle
Hypotenuse is the line opposite the right angle

These are math functions, but are introduced from their use in relating the sides of right triangle. If the right triangle is ABC with the right angle being angle B, AC is the hypotenuse, AB and BCare two sides. Now consider the angle A . Sin A= BC/AC, Cos A=AB/AC and Tan A=BC/AB. From this you get the soh\cah\toa, where o is opposite side and a is adjacent side and h is hypotenuse.
The functions can be used in non-right triangles also.

it is used to find the angles and sides of triangles when there is only like 2 sides and 1 angle

they are primarially used to determine the legeth of an unknown side of a right triangle (actual triangle or synthetically created).
Sine = opp/hyp
Cosine = adj/ hyp
Tangent = opp/adj
opposite
adjacent
hypotneuce
